Lying like a bow comes from a folk proverb: stand like a pine, sit like a bell, walk like the wind and lie like a bow. It refers to the three correct postures of sitting, standing and lying: standing straight as loose, sitting straight as a bell, and lying bent as a bow.

There are three main sleeping positions: supine, prone and lateral. The body is only half-moon, lying like a bow. This kind of sleeping method was regarded as "side sleeping" by the ancients.

The correct orientation of people when they sleep:

People should sleep with their heads facing north and their feet facing south. This is because the earth itself has a geomagnetic field, and the direction of the geomagnetic field is north-south (South Pole and North Pole). Magnetic field has the property of attracting iron, cobalt and nickel. The human body contains these three elements, especially the blood contains a lot of iron. Choosing the head, north foot and south direction to sleep can conform to the magnetic field lines, make the magnetic field lines pass through the human body smoothly, minimize the interference of geomagnetic field to the human body, and make sleep more sweet.

Chinese medicine also believes that people should sleep with their heads facing north and their feet facing south. The explanation is that with this sleeping orientation, the direction of qi and blood in the human body is consistent with the direction of the earth's magnetic field lines, which is easy to make qi and blood smooth, reduce metabolic rate and reduce energy consumption, and naturally feel refreshed when you wake up.
